Dependency of bridging traction of DCB composite specimen on interface fiber angle

In this paper, the role of interface fiber angle on the bridging traction of double cantilever beam (DCB) specimens is investigated experimentally. In order to eliminate the effect of the remote ply orientation on the bridging traction during delamination initiation and propagation, DCB specimens with stacking sequences of [011/θ//012] where θ = 0, 30, 45 and 90 were considered. An experimental test set-up was established for measuring the...
